CHAPTER 4 PORT FUNCTIONS

4.2.2
Port 3
Pins P30 and P31 constitute a 2-bit I/O port with an output latch. Each bit of this port can be set to the input or
output mode by using port mode register 3 (PM3). When the P30 to P31 pins are used as an input port, an on-chip
pull-up resistor can be connected in 1-bit units by using pull-up resistor option register 3 (PU3). This port is also used
for both timer I/O and external interrupt request input pin functions.
Reset signal generation sets port 3 to the input mode.
P34 is a 1-bit input-only port. This pin is also used as a RESET pin, and when the power is turned on, this is the
reset function. For the setting method for pin functions, see CHAPTER 17 OPTION BYTE.
When P34 is used as an input port pin, connect the pull-up resistor.
Figures 4-3 to 4-5 show the block diagrams of port 3.
